Referring to fig. 6, 7 and 8, the bird spike 130 includes a first spike 132, a second spike 134 and a third spike 136. When the bird spike 130 is in a combined state, the first spike 132, the second spike 134 and the third spike 136 are sequentially connected, and the third spike 136 is connected to the rotating mechanism 120; when the bird thorn 130 is in the split state, the first puncture needle 132, the second puncture needle 134 and the third puncture needle 136 are respectively positioned in the plurality of accommodating chambers. Wherein the second lancet 134 of each bird spike 130 can be provided with a specific number of knots as desired. In the present embodiment, each bird spike 130 includes 1 section of first spike 132, 2 sections of second spike 134 and 1 section of third spike 136, and each bird spike 130 is divided into 4 sections, so that 4 accommodating chambers are provided correspondingly, and the first spike 132, the second spike 134 and the third spike 136 are placed in the first accommodating chamber 127, the second accommodating chamber 128 and the third accommodating chamber 129, respectively. In other embodiments, the number of knots of the second lancet 134 can be increased or decreased to lengthen or shorten the length of the bird spike 130 to meet different needs.

In addition, the bottom cross section of the first spike 132 is slightly smaller than the top cross section of the second spike 134 and the bottom cross section of the second spike 134 is slightly smaller than the top cross section of the third spike 136 to facilitate the sequential combination and disassembly of the first spike 132, the second spike 134 and the third spike 136. Correspondingly, the cross sections of the first accommodating chamber 127, the second accommodating chamber 128, and the third accommodating chamber 129 are also gradually increased in sequence. Meanwhile, the top end of the first puncture needle 132 is in a sphere shape, so that birds or operators are prevented from being scratched; the bottom end of the third lancet 136 is provided with a clamping portion 137 which mates with a clamping portion provided at the upper portion of the third housing chamber 129. The clamping portion 137 is used for fixing the position of the third puncture needle 136 when the bird thorn 130 is in the combined state.

The locking mechanism 140 includes a pin 142 with a spring and a slot 144 matching the pin 142, the pin 142 is disposed at the bottom ends of the first and

second lancets

third lancets

134, 136. Specifically, a first pin 143 with a spring plate is arranged at the bottom end of the first puncture needle 132, a first connection part 135 connected with the first puncture needle 132 is arranged at the top end of the second puncture needle 134, the first connection part 135 has a sleeve structure, and a first clamping groove 145 matched with the first pin 143 is arranged at the first connection part 135; the bottom end of the second puncture needle 134 is provided with a second pin 146 with a spring plate, the top end of the third puncture needle 136 is provided with a second connecting part 139 connected with the second puncture needle 134, the second connecting part 139 is of a sleeve structure, and the second connecting part 139 is provided with a second clamping groove 147 matched with the second pin 146. When the bird spike 130 is in the combined state, the first pin 143 is clamped in the first clamping groove 145, and the second pin 146 is clamped in the second clamping groove 147, so that the first spike 132, the second spike 134 and the third spike 136 are sequentially and firmly connected, and the bird spike 130 is locked in the combined state.

The detachable bird thorn 130 can be switched between the detached state and the combined state by the rotation of the rotation mechanism 120 and the cooperation of the telescopic adjuster 123.

The unlocking mechanism 150 comprises an unlocking button 152 and an extrusion piece 154, wherein the unlocking button 152 is arranged on the shell 110, and the extrusion piece 154 is arranged at a position corresponding to the through hole 118 in the inner wall of the shell 110. The unlocking button 152 is connected to a pressing member 154, and the pressing member 154 is used to press the pin 142 under the driving of the unlocking button 152, so that the pin 142 is separated from the corresponding clamping groove 144, and the first lancet 132, the second lancet 134 and the third lancet 136 are separated. The extrusion 154 may be provided with different configurations as desired. In this embodiment, the pressing member 154 is a contact with a spring, and the spring drives the contact to apply force to the pin 142 of the locking mechanism 140 under the driving of the unlocking button 152, so that the pin is separated from the clamping groove 144, and the bird thorn 130 is unlocked from the combined state.

In addition, the bird preventing device 100 further includes a base 160, the housing 110 is mounted to the base 160, and the bottom plate 114 of the housing 110 is connected to the base 160. Base 160 is used to secure bird protection device 100 to a tower cross arm.

The working principle and working process of the bird prevention device 100 are as follows:

when the bird thorn 130 is in the split state, the first puncture needle 132, the second puncture needle 134, and the third puncture needle 136 are respectively placed in the plurality of accommodating chambers. Wherein the top end portion of the first spike 132 extends out of the housing 110 and overlaps the through hole 118.

The handle at the top end of the rotating shaft 121 rotates the rotating shaft 121 in a direction in which the inclined surface 126 of the protruding block 125 is lowered, so that the rotating shaft 121 drives the turntable 122 to rotate counterclockwise (in a top view) relative to the housing 110. Under the action of the relative movement of the housing 110 and the projection 125, the bottom end of the first spike 132 moves from the first accommodating chamber 127 in a clockwise direction along the expansion slot 124. Since the inclined surface 126 of the protrusion 125 gradually rises in the clockwise direction, the bottom end of the first spike 132 moves clockwise and the position thereof gradually rises, and the portion of the first spike 132 originally located in the housing 110 gradually penetrates the housing 110.

When the bottom end of the first spike 132 reaches the second accommodating chamber 128, the bottom end of the first spike 132 falls into the second accommodating chamber 128 due to the increased cross section of the second accommodating chamber 128, the bottom end of the first spike 132 falls into the first connecting portion 135 at the top end of the second spike 134 by the falling inertial force, and the first pin 143 is clamped into the first clamping groove 145 of the second spike 134 by the elastic force of the elastic sheet, thereby completing the connection between the first spike 132 and the second spike 134.

Continuing to rotate the dial 122, the first lancet 132 carries the second lancet 134. Similarly, the bottom end of the second lancet 134 continues to move clockwise from the second receiving chamber 128 along the expansion slot 124. While the bottom end position of the second spike 134 is raised and the portion of the bird spike 130 extending out of the housing 110 is gradually increased. When the bottom end of the second spike 134 reaches the next accommodating chamber, the second spike 146 is clamped into the clamping groove 144 at the top end of the next spike by the aid of the elastic force of the elastic piece by utilizing the falling inertia force, so that the upper spike and the lower spike are connected, and the next spike is driven to rise gradually. This is cycled until a final third lancet 136 is attached.

When the bottom end of the third lancet 136 reaches the upper portion of the third accommodating chamber 129, the engaging portion 137 of the third lancet 136 engages with the engaging portion of the third accommodating chamber 129, and the rotation of the turntable 122 is stopped. Thus, the assembly process of the bird spike 130 is completed and the bird spike 130 is locked, so that the bird spike 130 finally protrudes out of the housing 110 almost completely, and the state is stably maintained, thereby ensuring the normal operation of the bird preventing device 100.

When the bird thorn 130 needs to be restored to the disassembled state, the handle at the top end of the rotating shaft 121 is utilized to rotate the rotating shaft 121 in the direction of lifting the inclined surface 126 of the protruding block 125, so that the rotating shaft 121 drives the turntable 122 to rotate clockwise (according to the overlook angle) relative to the shell 110. The clamping portion 137 of the third spike 136 is disengaged from the clamping portion and falls, and the portion of the bird spike 130 protruding from the housing 110 is gradually shortened. When the bottom end of the second lancet 134 reaches the corresponding through hole 118, the unlocking button 152 is pressed, and the contact of the pressing member 154 provided on the inner wall of the housing 110 applies force to the second pin 146 of the locking mechanism 140 so as to disengage from the second clamping groove 147 on the top end of the third lancet 136, the third lancet 136 is disengaged from the second lancet 134, and the third lancet 136 falls into the third accommodating chamber 129.

Continuing to rotate the rotary table 122, the bottom end of the second spike 134 moves along the telescopic slot 124 from the third accommodating chamber 129, and as the inclined surface 126 of the protruding block 125 gradually decreases in the counterclockwise direction, the position of the second spike 134 gradually decreases while the portion of the bird spike 130 extending out of the housing 110 gradually decreases. When the bottom end of the last lancet reaches the through hole 118, the unlocking button 152 is pressed again, the second lancet 134 is unlocked from the last lancet, and the second lancet 134 is disengaged and falls down to the second accommodating chamber 128. This cycle is continued until the bottom end of the first lancet 132 is completely unlocked.

After the first lancet 132 is unlocked, the turntable 122 continues to be rotated, and the bottom end position of the first lancet 132 moves along the expansion slot 124 until reaching the first accommodating chamber 127. So far, the splitting process of the bird thorn 130 is completed, except that the top end part of the first puncture needle 132 extends out of the shell 110, and the rest parts of the bird thorn 130 are all positioned inside the shell 110, so that the operation of personnel is prevented from being hindered during transportation, installation and electric power overhaul.

The bird preventing device 100 adopts the detachable bird thorn 130, under the common cooperation of the rotating mechanism 120, the locking mechanism 140 and the unlocking mechanism 150, not only can the normal bird preventing work of the bird preventing device 100 be ensured, but also the bird thorn 130 can be contracted when needed, so that the transportation, the installation and the subsequent maintenance of power equipment are convenient.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art.
